Manufacturer claim
- Manufacturer sound data: 139 dB at the shooter's ear with M855 ammunition on a 10.3″ barrel.
- 60% less back pressure results in less toxic gas in the operator's face, improved reliability, superior recoil control, and a cleaner firearm
- SureFire measured 139 dB at the shooter's ear with a 10.3" barrel firing M855.
- Backward compatible with millions of SureFire SOCOM Fast-Attach® muzzle devices already in the field

- Low-back-pressure design reduces back pressure by 60% compared to conventional suppressor designs — less toxic gas in the shooter's face, improved reliability, superior recoil control, and a cleaner-running firearm.
- All-new muzzle design improves gas flow and significantly reduces flash, with flash suppression holding from the first round to subsequent rounds even when the suppressor is hot; the beefed-up muzzle also improves durability against front-end impacts.
- Measures 6.3 inches long and adds only 3.8 inches to the firearm; actual added length varies depending on which SureFire adapter is used.
- Next-generation SureFire gas flow dynamics further reduce flash signature
- Patented, tool-less Fast-Attach® design allows quick, easy attachment and removal
- Proudly designed and manufactured in the U.S.A.
- Built entirely from U.S. mill-certified Inconel superalloy, combining machined and 3D-printed aerospace-grade components with CNC laser welding.
- 100% Inconel construction delivers the combat-proven reliability and durability that established SureFire's SOCOM suppressor legacy
- SureFire finishes the SOCOM556-RC4 with a Cerakote™ Finish coating.
- Revised muzzle design provides greater durability when subjected to extreme abuse
- Backward compatible with SureFire SOCOM Fast-Attach muzzle devices already in the field; optimized for SF3P, FH556RC, and WARCOMP open-tine flash hiders.
- Optimized for 10.3-inch and longer barrels, the SOCOM556-RC4 is 6.3 inches long and adds only 3.8 inches to the firearm for minimal impact on handling characteristics
- Optimized for SF3P, FH556RC, and WARCOMP open-tine flash hiders
- Optimized for 10.3-inch and longer barrels.
